To all whom it may concern:

'Be it known that I, CARL Gnsrnv Sonne- KAT, acitizen of the UniteStates, residing at Fremont, in the county of Sandusky, State of Ohio,have invented certain new and useful Improvements in Safety-Razors; andI do declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures or" reference marked thereon,which form a part of this specification.

This invent-ion relates to razors of the safety type, wherein a thinblade is movably held in position with its cutting edge adjacent a guardwhich projects beyond the edge of the bladetto prevent cutting the face,it being customary to furnish with razors of this type a number ofblades so that when a blade becomes dull, a sharp blade may be quicklysubstituted therefor; and the invention consists in the construction andarrangement of parts hereinafter more fully set forth. and. claimed.

The primary object of the invention is to produce a razor of thecharacter described, of comparatively simple and inexpensiveconstruction, wherein the arrangement is such as to enable a bladehaving two cutting edges to be supported in amanner to render itadaptable for use, and at the same time enable the blade to be easilyinserted and quickly removed.

A. 'further object is to provide means for supporting a blade having twocutting edges without injury to the cutting portion of .either edge ofthe blade, and in a manner to enable the blade to. be readily handledfor insertion and removal without danger of cutting the hand. I

A further object is to provide a holder for the blade of suchconstruction that the blade shall be supported at its ends only, theintervening portionof the frame between the supporting ends whichcarries the guard teeth, being, depressed so as to afford a spacebetween the edge of the blade and the guard for the passage of hair andlather, the blades employed being sufficiently rigid to render themoperative for shaving without any support except at their extreme ends.

A further object is to provide means for positioning the blade in theholder and maintainin the cuttin edo'e thereof alb b 0 ways straightwith theguard.

A further object is to provide means for holding the blade yieldingly inplace with sufficient force to prevent movement of the blade during theoperation of shaving.

The above objects are attained by the structure illustrated in theaccompanying drawings, in which Figure 1 is a front elevation of a razorembodying my invention, showing the blade in position. Fig. 2 is a sideelevation thereof. Fig. 3 is an enlarged sectional view throughtheblade, the supporting-plate or frame and the guard, as on line 3-3 ofFig. 1. r Fig. 4: is a top plan view ofFig. 1. Fig. 5 is a similar viewshowing the position of parts during the operation of removing orinserting a blade. Fig. 6 is a top plan of the blade-supporting platewith the blade removed. Fig- 7 is a perspective view of the spring whichis mounted onthe back of the supporting-plate or frame and carries onits ends the angle brackets which engage the rear corners of the bladeand through the tension of the spring force the forward edge of theblade against the stop lugs on the end portions of the spring frame.FigfS' is a rear elevation of the razor. Fig. 9 is an end elevation ofthe blade. Fig. 10 is a longitudinal section as on line.'l010 of Fig.4:.

Referring to the characters of reference, 1 designates the handle, ofany suitable construction, having a reduced threaded stem 2. The frameor blade-holding plate Ei'is oblong and quadrangular in form, having adependin back portion 4 terminating in a reduced orwardly extending part5 which is provided with a tapped aperture to receive the threaded sternof the handle-where by the supporting-plate may be detachablymounted onthe handle, as shown. The central portion of the supporting plate isdepressed, as shown at (S, leaving the end portions 7 of said plateabove the plane of said depressed portion. The forward edge of thedepressed portion-of the plate between the supporting end portions 7, isprovided'with a plurality of teeth or downwardly curved fingers 8 whichform a guard that prevents the edge of the blade cutting the face, aswill be well understood in the art. By 'depressing the guard portion ofthe supporting-plate between the end portions 7 thereof, a space 9 (seeFig. 3} is formed between the when said blade is placed upon thesupporting-plate, whereby the blade may be held employed having thecentrally depending to theback 4 of the supporting-plate.

plane of said plate, as shown.

are not dulled or injured by the means of inserting it in or removingfrom the concaved, as shown at 17 in Fig. 6. to facili tatc the handlingof the blade in the manner f guard and the edge of the blade 10 whensaid blade is in position for shaving, affording a free passage for thehair and lather andpreventing the clogging of the lather between theguard and the edge of the blade, a result common in razors of this typewhere the blade rests directly upon the guard. An accumulation of latherbetween the teeth of the guard and the edge of the blade holds the bladefrom contact with the face and renders the razor inoperative until saidaccumulation is removed.

Upon the end portions 7 of the supportingplate at their outer edges areformed the' stop lugs 11 under which the forward edge of the blade atthe corners is adapted to engage, whereby the blade is caused to standin alinement with the guard and is held in proper relation thereto. Forthe purpose of pushing the forward edge of the blade against the stoplugs 11, a spring arm 12 is ear 13 which is riveted or otherwisefastened Said spring arm extends transversely across the back of thesupporting-plate and its end portions are curved forwardly, as shown at1%. Each of the forwardly curved end portions of said spring is providedwith a vertically extending cornpr bracket 15. Said brackets lie in theright-angle recesses 16 formed by cutting away the rear corners of thesupporting-plate and extend above the The shape of said brackets is suchas to cause them to embrace the rear corners of the blade only at itscorners, and at the same time properly positioned longitudinally. Thedistance between the stop lugs 11 and the brackets 15 is less than thewidth of the blade, so that to place the blade in the holder its rearcorners are caused to engage in" said brackets, when by applying arearward pressure to the blade, the spring arm 12 will yieldsufiiciently to allow the forward cor-. nersiof the blade to engageunder the stop. lugs 11, when by releasing the blade, the ten sion ofsaid spring arm will crowd it forward against said lugs and'hold it withsutiicient tension to maintain it in place during the ope- "ion ofshaving. It will be noted that tl stop lugs and the spring sup portedbrackets the blade only at the corners so that the cutting edges of theblade which holds the blade in place.

in. manipulating the blade for the purpose frame or holder, it isgrasped at the between the thumb and finger, the end portrons (iftheholder or sup portingplate being stated. By this arrangement a bladewith parallel cutting edges may be readily hell in a manner to enablethe blade to be. easily reversed when one edge becomes dull, therebyrendering the blade doubly serviceable with comparatively littleadditional expense,

the arrangement for holding the blade beingsimple and inexpensive and ofa character to prevent injury to the edge not in use while said blade isbeing held in operative position in the holder. The pressure e2:- ertedby the end portions of the spring arms against the rear corners of theblade is such as to crowd the blade forward against the stop lugs,thereby obviating the possibility of the cutting edge of the blade beingheld at an angle to the guard, and insuring a perfect positioning of theblade under all conditions.

Having thus fully set forth my invention what I claim 'as new and desireto secure by Letters Patent, is

1. In a razor, the combination ofa bladeholding member having a guardalong one edge, a blade having parallel cutting edges, stops upon theblade-holding member adapted to engage the forward corners of the bladefor alining said blade with respect to said guard, a spring arm mountedon the back of the blade-holding member having brackets at its ends toengage the rear corners only of said blade and press the blade forwardagainst said stops, said brackets having engagement also with the endsof the blade to prevent. longitudinal moven'ient thereof on theblade-holding member.

2.
